Beech Lake Dam, located in Warren County, Iowa, was completed in 1961 and serves primarily as a recreational structure. The dam, with a height of 25 feet and a length of 700 feet, holds a storage capacity of 514 acre-feet and covers a surface area of 43 acres. Situated on TR-COAL CREEK near the RED ROCK RESERVOIR, the dam is owned privately but regulated by the Iowa Department of Natural Resources (DNR) and subject to state inspection and enforcement.

Despite being classified as having a low hazard potential, Beech Lake Dam is considered to have a moderate risk level, with a risk assessment rating of 3. The dam is primarily constructed of earth and sits on a soil foundation. Although the dam does not feature a controlled spillway, it is equipped with emergency action plans (EAP) to ensure proper response in case of an emergency. The dam is not under the jurisdiction of the US Army Corps of Engineers and has not been rated for its condition, but continues to be regularly inspected by state authorities to ensure its safety and functionality for water resource and climate enthusiasts to enjoy.
